Instead of notifying authorities, the report says administrators spent months conducting their own informal investigation, even using a student to run surveillance on Watkins.

Starting next week, the school board will start looking at what policies to change and whether anyone, including the superintendent, should lose their jobs.

The district says all staff have been retrained on mandatory reporting requirements.

The report blames much of the alleged cover-up on what it calls a "culture of fear" in Stamford schools. Many teachers told investigators they were afraid of retaliation if they spoke up about problems.
